  The SAP error message RSRTS_CDS019 indicates that there is an issue with the order by clause in a query that is using Core Data Services (CDS) views. This error typically arises when the system encounters an unresolved order by entry in the query definition, which means that the specified order by field is not recognized or cannot be resolved in the context of the query.
  Cause:
  
  Invalid Field Reference: The field specified in the order by clause may not exist in the CDS view or may not be part of the selected fields.
  Aggregation Issues: If the query involves aggregation, the fields used in the order by clause must be part of the aggregation or must be included in the group by clause.
  Incorrect Syntax: There may be a syntax error in the query definition that prevents the system from correctly interpreting the order by clause.
  Data Model Changes: Changes in the underlying data model or CDS view definition may lead to fields being removed or renamed, causing the order by clause to reference non-existent fields.
  
  Solution:
  
  Check Field Existence: Verify that the fields used in the order by clause are present in the CDS view and are correctly spelled.
  Review Aggregation Logic: If the query involves aggregation, ensure that the fields in the order by clause are either aggregated or included in the group by clause.
